组织培养是种植业中较为先进的应用技术,它既能缩短育种周期,尽快地进行“亲一子”鉴定,同时能扩大繁育系数,使新培育的优良品系快速投入生产。近几年来在我国的农林业生产中应用范围越来越广,取得了良好的效益,有力地推动了生物科学中高新技术的发展。为了完善学生的知识结构,熟悉了解组织培养的基本知识和技能,中专林木育种学教学大纲纳入了此项内容。完成一个组织培养的全过程需要4～5个月的时间,而大纲规定在4个学时内讲完此项内容。如何在有限时间内完成教
Tissue culture is a more advanced application technology in crop industry. It not only can shorten the breeding cycle, carry out “pro-one” identification as soon as possible, but also expand the breeding coefficient so that the newly cultivated fine lines can be quickly put into production. In recent years, the application range of agroforestry in our country is more and more wide, which has achieved good benefits and effectively promoted the development of hi-tech in the biological sciences. In order to improve the student’s knowledge structure, familiar with the basic knowledge and skills of tissue culture, secondary school forest tree breeding teaching program incorporated this content. It takes four to five months to complete the whole process of organizational training, and the outline provides that the content is completed within four hours.
